crypto: aes - Add CTR and XCTR support using library

Browse source

Implement the "ctr(aes)" and "xctr(aes)" crypto_skcipher algorithms
using the corresponding library functions.

Among other benefits, this allows the architecture-optimized AES-CTR and
AES-XCTR code to be migrated into the library while still leaving it
accessible via crypto_skcipher, eliminating lots of boilerplate code.

For now the cra_priority is set to just 110, since the
architecture-optimized implementations of these algorithms haven't yet
been migrated into the library.  It will be boosted once that happens.
